The State Belt Railroad of California was a shortline that served San
Francisco's waterfront until the 1990s and played an important role in
World War II. Its tracks extended the length of the Embarcadero from south
of Market Street to Fort Mason and the Presidio. The Belt transferred
cargo between ships and main line railroads such as the Southern Pacific,
Western Pacific and the Santa Fe. It also loaded trains onto car ferries
for ports across the Bay. Although locals nicknamed the line the Toonerville
Trolley and the Wooden Axle Line, the State Belt had an illustrious career.
The first section of the State Belt was built by the Board of State Harbor
Commissioners in 1890. In 1913, the State Belt built the Belt Line Engine
House, a five-stall roundhouse at Sansome Street and the Embarcadero in
San Francisco. This engine facility housed a modest number of oil-fired
steam switchers, and later, ALCO S-2 diesels. An accessory building to
the engine house, the sandhouse, was built the following year. Both buildings
are simple utilitarian buildings of this period, constructed with reinforced
concrete and plaster. The buildings were altered in the 1950s replacing
five main doors with industrial type roll-up doors set back from the façade.
Renovation work done in 1984 included replication of the original doors
and reinstallation in their original location.

In 1914, the State Belt tracks were extended on a wooden trestle across
a shallow stretch of the Bay known as Black Point Cove. There, at the
end of Van Ness Avenue, a new railroad tunnel built by the Army took
the track under Fort Mason to the dock area on the fort's western edge.
The Army's railroad went on to the Presidio, and was used through World
War II and beyond to transport supplies, and occasionally troops.

The State Belt contributed greatly to the movement of materials during
the war. Army and Navy switchers were added to provide enough locomotive
capacity. The State Belt also delivered trainloads of fresh troops to
debarkation points, and picked up hospital trains and returning troops.The
railroad moved 156 troop trains and 265 hospital trains in 1945 alone.

Today, the former Belt Line Railroad and Sandhouse have been converted
into office space. Although the Belt Line ceased operations in 1993, the
success of the recently established Market Street Railway F-Line along
the Embarcadero to Fisherman's Wharf has prompted a movement to extend
the historic streetcar line to serve several historic attractions beyond
the current terminal, including San Francisco Maritime
National Historic Park, Fort Mason and the Presidio.

The Belt Railroad Engine House and Sandhouse is bounded by Lombard,
Sansome and the Embarcadero in San Francisco. The building is now private
office space, and is not open to the public. For more information on
the proposed extension of the historic streetcar line, visit the Market
Street Railway's website. Visitors may also be interested in the
nearby Golden Gate
Railroad Museum, which houses State Belt Steam Engine #4 (built
in 1911).
